v. QUALITY ASSURANCE. Both inspections shall
on the Final Test Sheet, paragraph 14,
Table 4 (Final Acceptance Test Procedure).
Perform an in-process inspection before the panels and doors are installed.
After PMCS, testing, and painting have been completed, perform a quality assurance final
inspection. Inspect test data sheets and all the parts, components, and problems identified in
the Technical and Functional Inspections; repair as needed. Perform Operator and Unit
PMCS inspections. Upon successful completion of the QA inspection, PM AGSE will certify
the AGPU for re-issue to the field, unless PM AGSE delegates this responsibility to a QA
9. SUPPLY/PARTS AND DISPOSITION. N/A
OF RUST AND CORROSION.
As an aid
in evaluating rust damage and planning rust repair actions, rust shall
be classified into
Stage 1 Red, black, or white corrosion deposits on surface accompanied by minor etching
and pitting. Base metal is sound.
Stage 2 Powered, granular, and scaled condition resulting in erosion of material from the
surface. Base metal is sound.
Stage 3 Surface condition and corrosion deposits are similar to Stage 2, except that metal
in the corroded areas is unsound and small pinholes may be present.
Stage 4 Corrosion has advanced to a point where the surface has been penetrated. No
metal remains at point of severest corrosion. There are rust holes in the surface area, or
metal is completely missing along the edge.
b. Exterior surfaces of units with areas of Stage 1 or Stage 2 rust shall be blasted, cleaned, treated,
primed, and painted. Units with areas of Stage 3 or Stage 4 rust shall be repaired, cleaned,
treated, primed, and painted in those areas or should have assemblies replaced with new
assemblies if repair is not economical.
c. Any evidence of corrosion on working surfaces of close tolerance parts is not acceptable. Pitting
or surface deterioration in the area of any seal or gasket is not acceptable if it affects the proper
functioning and/or proper performance of the applicable component.
